Interpretive Summary: Bacterial wilt, a disease of common bean, is caused by the bacterium Curtobacterium flaccumfaciens pv. flaccumfaciens. Since the mid 2000’s, reports of bacterial wilt outbreaks have become more common, including in bean-growing regions where the disease has not been a significant problem since the 1970’s. Unlike other bacterial pathogens of common bean, very little genomic data are available for strains of C. flaccumfaciens pv. flaccumfaciens. In this work, five strains of C. flaccumfaciens pv. flaccumfaciens were isolated from symptomatic plants originating in Turkey. All five strains induced wilt disease on three different common bean cultivars in greenhouse tests. The complete genome sequence for one strain was determined, providing a useful genomic resource for future studies.

Technical Abstract: Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff) is the causal agent of bacterial wilt of common bean (Phaseolus vulgaris), a disease that can impact common bean production worldwide. Current genomics resources for this important bacterial pathogen are limited. Therefore, long-read sequencing was used to determine the complete genome sequence of a pathogenic Cff strain isolated from common bean leaves showing irregular necrotic lesions with yellow borders collected in a commercial field in Turkey in 2015.
